This thing works! Amazing results. I put my semi erect penis into the Robot Suck and it turns into a hammer. Added 2". Be careful though use must use the relief valve or it feels like the head is getting a hickie.

I was never able to masterbait by myself I would always have difficulties with the masterbaiting portion but with the robo suck I can blast off whenever I want and for how small it is I can get away with using it at work

This product lived up to the expectation I had. It's a nice quality penis pump. For thoes with a price Albert ring I suggest using a bigger diameter ring when using a penis pump. This pump will make you com hard
